The house was built in the mid-1970s and the windows had never been touched. Single-pane glass in wood frames that had spent forty-five years expanding and contracting through Northern Virginia summers and winters. The homeowner in Burke described the symptoms before we ever saw them: rooms that never held heat, frames painted shut, condensation between nothing because there was only one pane, and a draft you could feel from across the room.

When we arrived, the diagnosis was straightforward and the complications were too. This was not a simple swap.

What forty-five years does to a window

Three problems stack up on an original window of this era. The glazing is single-pane, so it offers almost no insulation and the energy loss is constant. The wood frames had taken on moisture over decades and several sills had rotted soft, especially on the weather-facing elevations. And because the house predates the 1978 ban on lead-based paint, the existing coatings had to be treated as lead-containing and handled accordingly.

That last point is where experience matters most. Disturbing lead paint carelessly is a health hazard, particularly in a home. Our crews follow lead-safe work practices: containment, controlled removal, and proper cleanup, so the old coatings come out without contaminating the home.

The replacement

We measured every opening individually, because a forty-five-year-old house has settled and no two openings are identical anymore. The rotted sills and frame sections were rebuilt to give the new units a sound, square, dry opening to seat into. We installed modern double-pane, Low-E, argon-filled replacement windows sized to each opening, then sealed and insulated the perimeter so the air and water barrier was continuous.

The difference was immediate. The drafts were gone, the rooms held temperature, and the homeowner stopped hearing the street through the glass. A 1970s house finally performed like a modern one without losing the colonial character of the elevation.

Why 25-plus years of window work matters here

DreamHome has been installing windows in Burke and across Northern Virginia since 1999. An old colonial is not a catalog install. The openings are out of square, the frames hide rot you cannot see from the curb, and the lead paint adds a layer of care that a fast crew will skip. Twenty-five years of doing this means we plan for the rot, the settling, and the lead before the first window comes out, so the project stays clean and on schedule.

If your home still has its original windows

• Single-pane is costing you every month. The energy loss on original 1970s glazing is constant, summer and winter.
• Expect hidden rot. Weather-facing sills on older homes are usually soft underneath the paint. Plan for the repair.
• Pre-1978 means lead-safe handling. Insist your installer follows lead-safe work practices.
• Every opening gets measured. A settled house has no standard openings left. Custom-sized units are the only right answer.
